Look closely and consider picking up flight (8)
I believe the answer is:
stairway
'flight' is the definition.
(flights of stairs)
'look closely and consider picking up' is the wordplay.
'look closely' becomes 'stair' (I am not sure about this - if you are sure you should believe this answer much more).
'and' is a charade indicator (letters next to each other).
'consider' becomes 'weigh' (as in weighing something up).
'picking up' shows a homophone (sound like).
'weigh' is a homophone of 'way'.
'stair'+'way'='STAIRWAY'
Can you help me to learn more?
(Other definitions for stairway that I've seen before include "- to Heaven, Led Zeppelin song" , "A flight of fixed indoor steps" .)
